In the Cinebench R20 single-threaded test, we see a result of 646 points, which is exceptional for any CPU. This is a significant improvement over the older Ryzen 9 3900X.
In this test, we see a score of 9224 from the overclocked 5900X. Compare that to the 8414 of the 5900X at stock speeds and the improvement is relatively solid. Now, compared to the 7251 of the 3900X, the difference is substantial. The 11900K simply falls flat on its face here.
In Cinebench R23’s single-thread test, we see a smaller gap across the test systems. The 5900X while overclocked manages only a small lead over the stock 11900K, but achieves a decent gain over the 5900X at stock speeds. The Ryzen 9 3900X falls behind everything else here.
In the multi-thread test, the 5900X far outstrips its predecessor here. Oddly, it’s faster at stock speeds than overclocked. This is a test that traditionally favors manual overclocking on CPUs with larger core counts. The 11900K gets beaten pretty badly here as its core count is just too low to compete.
